Under normal circumstances u can copy a copy, but as TacoBill mentioned, the makers of DVDxCopy made it so you cannot copy the backup created by their software. It puts in some kind of encryption to keep you from starting yer own DVD movie factory.

The huge lawsuit with the MPAA resulted in that little add-in I'm sure.

Why anyone would want to use that software is beyond me. 10 minutes of scanning thru any DVD burning message board should provide plenty of reason not to waste money on it.
